How can the radian measure of an angle determine the arc length on the unit circle?

The radian measure IS the arc length of the unit circle, by definition - that is how the radian is defined in the first place.

What is a radian fundamentally made of?

It is a measure of the extent of angular displacement - a measure of an angle.

Radian measure of an angle at 72 degrees?

1.256 radians.

What is the radian measure of the angle 72?

72 degrees = 1.256637 radians.

How do you define radian?

An informal definition: If you take a radius of a circle and wrap it around its circumference then the angle which that arc will make at the centre of the circle is 1 radian.More formally, a radian is 1/(2*pi) of a whole angle.

What is the radian measure of an angle whose measure is -420?

x*pi / 180 -420*3.14 / 180 = -7.33

Angle measure given in radians?

To get radian measure of angle given in degrees, multiple the measure in degrees by PI/180. Example: 60 deg = 60 * PI/180 rad = 1.047 rad.

What is the radian measure of an angle whose measure is 420?

It is 420/180*pi radians = 2.33... *pi radians or 7.3304 radians (approx).
